Although epoxy resin was developed from liquefied sustainable resources, such as wood, corn bran, bagasse, etc., the use of liquefied biomass for manufacturing high performance epoxy resin has been limited because of the effects of these materials on properties of epoxy resin were unclear. Thus, the liquefied reed-based epoxy resin was synthesized by glycidyl etherification between liquefied reed and epichlorohydrin in this study. The relationship between reed liquefaction behavior and thermodynamic properties of liquefied reed-based epoxy resin was investigated by Gel permeation chromatography (GPC) and Thermogravimetric analysis (TGA), as well as by determination of residue content, phenol content, epoxy index and mechanical performance. The results indicated that not only high content of bound phenol, but also broad molecular weight distribution of liquefied reed would widen molecular weight distribution of synthetic epoxy resin, which was a major cause of low adhesive shear strength and great thermal stability of cured resin.
